Homer certainly contributes to the modest revenue of the bar, but Barney Gumble seems to be the heaviest drinking patron. One wonders, however, whether Barney purchases as much beer as he steals.

The beer of choice at Moe's Tavern, and indeed in Springfield, is Duff Beer. The neighboring town of Shelbyville prefers Fudd Beer, but nobody at Moe's would be caught drinking that crap. Once, when Homer came into some money, Moe tried to pass off Springfield's favorite ale as a fancy imported beer that he pronounced "Doof" by placing an umlaut over the "u" on the word "Duff."

Once or twice on the show Moe's Tavern had been likened to the famous Cheers bar. Many historic events in Springfield have happened at Moe's Tavern. For instance the last concert of the Be Sharps occurred there. All in all, Moe's Tavern is an integral part of The Simpsons' life in Springfield.
